{"version":"1.0","type":"rich","title":"Interactive Visualisation","description":"A treemap visualizes hierarchical sales data from a UK sales CSV, with regions and towns nested by country. Users hover over rectangles to see a breadcrumb showing the region, town, and total sales value. Built with React and D3 v7, the chart uses `d3.stratify`, `d3.treemap`, and `d3.scaleOrdinal` to structure and color the hierarchy, while SVG rendering and `mouseenter` events drive the interactive labels and layout.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1befc18bc5244d39ba5186c4bf69ae48?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
